sHOE BEPAIR MACHINE.

The invention'relates to shoe repair machines, especially adapted foruse in shoe repair shops. i

7 An object .of the invention is to provide a simple and eifectivemachine for severing the stitches in the edges ofa shoe -solepre'paratory to repairing the same.

Another object of the-invention is to' provide such a machine capable ofmanual manipulation.

Another object of the invention is to provide a simple. and effectivemachine for this purpose which is capable of economical production.

Another object of the invention is toprovide such a machine capable foruse inmaking ornamental stitch impressions in the edges of a shoe sole;

Other objects and vention will appear more The invention consists in thecombination and arrangementof parts and in the'method of procedurehereinafter described and claimed.

In general the objects of the invention are attained by providinga'revolving table and a cooperating feed wheel adapted to 'engage theedge of a shoe sole on said table and intermittently feed the same byrevolving said shoe and table. Co-operating with said table novelfeatures of the inand feed wheel is a reciprocating knife ar-' ranged tosever the stitches in the edges of the shoe sole as it is thus fedto'the knife. Attachments are also provided whereby a knurled orserrated impression wheel may be readily mounted on said feed wheel anda yielding revolving table substituted for said first mentioned table,means for yieldingly pressing said yielding table toward said impressionwheel being also provided, whereby ornamental stitchimpressions may bemade in th'e'edges of a repaired shoe sole if desired.

The invention will be best understood by accompanying drawings forming apart of this specification, and in whichi Fig. 1 is a side view of amachine embodying the invention; 3 i

Fig. 6 a detailview of the feed wheel. of

the machine and co-operating parts;

Fig.7 a view similar to Fig. 3 but show-- ing a modified form ofconstruction, and

g. 8. a section. taken substantially on line 8-8of Fig. 7.

The form of construct on illustrated Figs. 1 to 6 inclusive comprises asuitable base or standard 10 having'a hollow supporting boss 11 formedintegrally therewith. A supporting stemor stud shaft 12 is removablysecured in the top of the boss 11 by means of a set screwv 13. Arevolving table 14 is mounted upon ball bearings 15.011 the top of thestud shaft 12 andwhereby said table, will readily revolve in a slightlyinclined position as best shown in Fig. 2. I I I A suitable frame 16 ispivoted at- 17 on two supporting lugs 18 on the base 10, a suitable stop19 being'provided on one of said lugs 18 to limit the backward swing ofsaid frame in .one direction. At its side opposite the pivot 17 theframe 16 carries a swinging and sliding bolt 20 slidable in a pivotedbracket 21 and carrying an I adjusting handle 22 threaded thereon toadjust the tension of a compression spring 23 as indicated The bolt 20carries a hook 2 1 adapted and arranged toengage teeth on av lug 25 onthe base lO and whereby the frame 16 may be adjustably and yieldingly,locked inoperative relation with the revolving table 14.

Mounted carrying a head 27 having a knurled. conical feed wheel 28mounted thereon in co-operative relationship with the edge of the table14:. The arrangement is such that the frame 16 in the frame 16 is ashaft 26 may be readily adjusted to cause the feed wheel '28 to engagethe edge of a shoe sole 29 on the table lt'and feed said edge of saidshoe sole by revolving said table as will be readilyunderstood. Theshaft 26 carries a ratchet wheel 30 co-operating with a ratchet arm 31loose on the shaft 26 and carrying a spring held pawl 32 enga 'ing saidratchet.

The pawl arm 31 is given a slot and pin connection 33 with one end of alever 3 1 fulcrumed on the frame 16 and having its other end connectedby a link 35 with a crank pin on an adjustable block 36. The block 36 isreadily shdable in a radial slot 37. in a wheel 38 and is adjustable insaid slot by means of an adjusting screw 39 as best shown in Fig. 5. Thewheel 38 is mounted on a shaft I 40 connected bya gear 41 also on shaft40 with a gear 42 on a crank shaft 43 operable by means of a hand crank44 and whereby adjustable movementmay bereadily imparted to the feedwheel 28 and the shoe sole 29.

The gear 42 also meshes with a gearf45 on a shaft 46 in frame 16. Shaft46 carries a crank pin 47 connected by a crank 48 with the upper end ofa reciprocating plunger 49 mounted in a bearing on the outer face of theframe 16 just above the feed wheel 28. A severing knife 50 is removablymounted in v the plunger 49 to operate immediately adjacent the side ofthe feed wheel 28. By this arrangement it will be apparent that a shoemaybe readily placed upon the table 14vand the edge thereof engaged bythe feed wheel 28. Upon operation of the crank 44 the edge of the shoesole will be intermittently fed step by step under the knife 50 and saidknife will be caused to impinge upon and sever the threads 51 in theedge of said shoe sole. By adjusting the block 86 in the slot 37 theextent of the feed of the feed wheel 28 may be varied for differentstyles of stitches. In this way, it will be noted, that the stitches inthe edges of a shoe sole may be readily severed and the sole removed forrepair purposes.

In the modified form of construction illustrated in Figs. 7 and 8, Ihave provided attachments whereby the machine .may be readily used formaking stitch impressions in the edge of the sole after a new sole hasbeen applied. To this end a revolving table 14 is provided with a stem12, smaller than before, and adapted and arranged to reciprocate freelyin the opening in the boss 11. Arranged in the boss 11 is a lever 52pivoted at 53 and projecting through a slot 54 at the side of said boss.7 52 is connected by the compression spring 55 with pressure arm 56 on alever 57 fulcrumed at 58 on one of the lugs 18 and whereby the table 14may be yieldingly pressed, upwardly by exerting manual pressure on thelever 57. A hollow fluted or serrated impression Wheel 59 isprovidedwith a hub 60 arranged to removably engage the head 27 on theend of shaft 26, a set screw 61 I being provided for securing saidimpression wheel in place. By this arrangement it will be observed thatthe knife 50 may be removed and a table with the sliding stem 12substituted for the permanently mounted table, and an impression wheel59 mounted upon the head 27, as shown in Fig. 8. When so equipped theedge of a shoe sole 29 may be placed on the table 14 under theimpression wheel 59 as indicated in Fig. 8 and ornamental stitchimpressions formed in the edge of the sole after the same has beenrepaired.

It will straighten a sole when wet and also draw the sole away from theupper to The other end of the lever straighten it after nailing a soleto the upper.

While a preferred embodiment .of the in-. vention has been illustratedand described, this is capable of variation and modification withoutdeparting from the spirit of .the invention. It is, therefore, notdesired to limit the patent to the precise details disclosed,

but to include therein such variations and modifications as fall withinthe scope of the appendedclaims.
